New climate bill signals growing support for methane policy

As recently as two years ago, methane leaking from the natural
gas supply chain was a niche climate issue, of concern to a handful of
scientists and policy experts who understood that small leaks could contribute
mightily to the global warming we’re experiencing now.

That has changed. A succession of scientific studies has confirmed that leakage rates in at least some
regions and parts of the supply chain are alarmingly high, and that extreme weather impacts can be made
worse by short-lived climate pollutants such as methane.

And now for a piece of good news: Policymakers are taking notice.

Last week, Democrat Senator Chris Murphy and Republican Senator
Susan Collins introduced the 2014 Super Pollutants Act. The bill calls for a new task force to oversee the reduction of super pollutants,
including methane, black carbon, and hydrofluorocarbons.

It directs the U.S. Environmental Protection Agency to create an
inspection program to fix and monitor the leakiest natural gas production
equipment. It would also require the Federal Energy Regulatory Commission to study
leaks and venting of methane across facilities it has authority over, such as
interstate natural gas pipelines.

Methane pollution is growing in part because of America’s increased oil and gas production; methane is the primary ingredient in natural gas.

The super-charged greenhouse gases targeted by the Senate bill don’t
last as long as carbon dioxide in the atmosphere, but in the case of methane, it
does 84 times more climate damage over the first 20 years after being released into the atmosphere.

Today, methane and other short-lived climate pollutants account for roughly one-third of the warming we’re experiencing.

Methane awareness is growing

The Super Pollutants Act faces and uphill battle on Capitol Hill. But the bill – and the strong bipartisan leadership demonstrated by
Senators Murphy and Collins – signals
a growing awareness of the methane issue in Washington.

It laid the groundwork for federal action with the creation of an
inter-agency task force that is evaluating opportunities for methane reductions
across the economy, including the oil and gas industry – the largest industrial
source of U.S. methane emissions.

In March, this task force released a
comprehensive roadmap for achieving significant methane reductions under
existing law. An important part of this
roadmap is a possible regulatory action
the U.S. Environmental Protection Agency under the Clean Air Act.

The methane
strategy also calls for action by other agencies: Before the end of the
year, the Department of Interior will decide how to deal with methane leakage
and natural gas waste from production on federal lands.

It’s heartening
to see methane getting the attention it deserves. Especially when we know with
certainty this is a problem we can tackle.

Other opportunities for methane action

An analysis by ICF International and sponsored by Environmental
Defense Fund found that there are many off-the-shelf, cost-effective
technologies that could cut methane emissions by 40 percent in the next five years.

Colorado’s air
rules are a model, demonstrating that there are smart, cost-effective ways to
regulate methane, ways that show ‘good for business’ and ‘good for the environment’ are not mutually exclusive.
Wyoming and Ohio also adopted policies in the last year to drive down oil and
gas air pollution.

You know so much its almost hard to argue with you (not
that I personally will need to…HaHa). You certainly put
a fresh spin on a subject which has been discussed for ages.
Great stuff, just great!
